External HD sometimes doesn't attach, how to re-probe?

I have this disk in an Icy Box connected via USB3:
da0 at umass-sim0 bus 0 scbus11 target 0 lun 0
da0: <ST4000DX 001-1CE168 CC44> Fixed Direct Access SCSI device
da0: 400.000MB/s transfers
da0: 3815447MB (7814037168 512 byte sectors)
Every now and then (1 in 10 or so), when I power-up the Icy Box, the
drive spins up, but the device nodes do not appear. I then try to
"camcontrol rescan all", restart devd and devfs, but it has no effect.
Invariably I end up power-cycling the Icy Box, which always works.
Is there a different way to "re-probe" disks connected via USB when
they fail to attach on the first try?
